To rf/Z/j whom, t may concern:

Beit known that l, STUART E. FREEMAN, a citizen of the United States, residinv at Barberton, in the county of Summit anState of Ohio, have invented certain new and useful Improvements in Grading and Ditching Machinos, oi which the following is a specification.

My invention relates to grading and ditch,

ing machines in which a plow is suspended for side tilt and other movementssuch, for example, as in patent to T. J. Gray, No. 743,487 dated November 10, NO3-the plow being preferably arranged and suspended by chains or cablcs,substantially as in said patent, which also includes means for laterally tilting the plow.

More specifically, my invention concerns the low-tilting means.

O jects of iny'invention are to provide sirnple and eflicient means for laterally tilting the plow and to permit it to have such other movements as it is understood to be capa1 ble of when thus suspended.

In the accompanying drawings, Figure 1 mainly illustrates my improved plow-tiiting device in elevation, the plow-beam and certain bars or sills of the body-frame being shown in cross-section on a vertical lane at one side of the plow-tilting device. 'g. 2 is a to plan of the plow-tilting device, the

han wheel shaft being in section on a hori zontal plane indicated by line :n :n in Fig. 1. Fig. 3 is a detail view produced b a section on line y fj in Fig. 1, the scale of ig. 3 being larger than in Fig. l. Fig. e is a detail showing in side elevation a portion of the plowbeam an'd the lower portion of the upright arm or bar secured thereto. Fig. 5 is ,a side elevation of a portion of a grading and ditchi machine embodying my invention.

he portion of the body-frame illustrated comprises sills A, which are longitudinally arranged as to the length of the machine and elevated relatively to the plow P. The plow has its standard 1 secured to the plow-beam2.

The plow is rovided with anu wardly-extending arm BP, formed by a ro or bar, the plow-beam 2 and the arm B being rigidly eld together by suitable means. The arm or bar B extends upwardly from the plow and is connected with a horizontally-arranged slide-bar l), Vsupported and guided by a suitable guideway lll, arranged and secured upon the longitudinal sills A of the body-frame of the machine. 'The arm B has an articulate-.i connection with the slide-bar l), which latter constitutes a shifter or reciprocative member for laterally tilting the arm B, so as to laterally tilt the plow. As a preierredarrangement the rod or arm B is connected with the bar D b ra universal joint consisting of a balland-soc et joint, the ball 3 being arranged in a socket formed within socket-pieces 4 4 on the bar D. `The ball 3 is also formed with a diametric opening 5, in which the arm B is fitted, the arm and said opening being polygenel-for exam le, rectangular, as shown.

As a means ihr shifting the reci rocative member D longitudinally it is provided with a line of teeth 8, engaged by a worm F on a rota worm-shaft 9, arran ed over the said mem er D. The worm an its shaft can be supported in any suitable mechanical way, and the said shaft 9 is provided at one end with a bevel-gear 10, which enga es a bevelgear 1i on an upright rotary sha t or rod G. The' shaft is convenienti Y mounted in bearings 12 and 13, supporte on the bodyframe, and the upper end of the shaft G is provided with some suitable device7 whereby 1t can be manually operated-such, for example, as a bandvfheel 14.

An attendant standing upon the usual platform on the body-frame can readily operate the shaft G, and thereby shift the reciprocative member I) in either direction, accordin to the direction in which the shaitG is turno The movement of the slideebar or reci rocative member D serves to tilt the arm and thereby tilt the low laterali to the line of progression, an the ball-and-socket joint permitsthe plow to have other movements incident to a low in a rading and ditching machine inw ich the p 0W is suspended by chains or cables, it'bein understood that the low is thus suspende The ball or socket )oint also ermite the arm B to tilt, while the member moves longitudinally. As illustrated, the lower end of the Hat bar forming 'arm B is bent and bolted to the lower flange of a channel-iron forming the plow bean1, said arm being also secured to the upper llange of the beam by a bracket 15.

In Fig. 5 the rear end of the plow-beam is shown suspended by a chain 16 passing under a sheave 17 on the plow-beam, one end ofthe chain being attached to a bracket 18 on the body-frame of the machine and the other end of said chain being attached to a winding-shaft 19, mounted upon the bracket 18. It is understood that the plow-beam is also suspended at a point forward of the plow b y another chain, and as chains for such purpose are common in the art and shown, for example, in patent to Gray, hereinbeforc mentioned, special illustration of' a suspendingchain forward of the plow is omitted.

That I claim as in v invention is 1. A plow-tilting device for grading and ditching machines comprisingr an arm secured to the plow and extending upwardly therefrom; a reciprocativc member with which the said arm has an articulated connection, and an operating gear device engaging teeth upon the reciprocative member.

2. A plow-tilting device Jfor grading and ditching machines comprising an arm secured to and extending upwardly from the plow; a reciprocative member arranged laterally to i said arm and having an articulated connection therewith; a worm-gear engaging wormteeth with which the reci rocative member is provided. and means or operating the worm-gear` 3%. A plow-tilting device for grading and ditching machines comprising an arm secured to and extending upwardly from the plow; a rcciprocative member having an articulated connection with said arm and provided with worm-teeth; a worm-gear engaging the wormteeth on the reciprocative member, and a roi taryY shaft or rod gear connected with the worm-shaft.

4. In a grading and ditching machine, a reciprocative member supported on the main frame; an arm B having a ball-and-socket connection with said reciprocative member g and a plow having its beam attached to the arm below the socket.
